stopping and self correcting was not terribly uncommon in the slimey glow days. It is quite humorous when you see it in person.

If only you could do it both directions while in flight....you would have the only variable pitch gas system EVER!!!!

But if it did it in flight when you didn't want it to....Hooo boy...Turbo Raven crash... At the beginning of the video the TV station says it was an engine failure, but it was not, Wayne would go to reverse pitch for the down leg of this maneuver, but on this flight, when he tried to go back to positive pitch, it did not do so...So, he pancaked the plane. Wayne did survive the crash, but is something like 1.5" shorter now do to all the spinal crushing...

Not the ignition....all ignitions spark when a magnet passes the hall sensor....they can not sense direction. It's in the intake/exhaust/spark timing combination...that particular engine happens to bounce off of the compression stroke on flips where it did not start.....and it fires on the "return" as it bounces through the compression stroke.....then it keeps going. Engines with less spark advance and not extremely aggressive intake/exhaust port timing have all of the "action" close enough to TDC that they will indeed run in reverse.....not as much performance in reverse of course...but it will run. Typically just getting the throttle in the "right" spot minimizes the problem.....but today I was starting with fresh radio programming.....

After the first real start, it was easy to zone in on the proper "idle" epa and then I was in fine shape for the rest of the afternoon....but that first time was interesting today...

What's causes the OS motor to start backwards. It's the only brand of engine I hear that does it? Is it something to do with ignition?

itit has to do with it being two stroke like bivens said...the old 2 stroke Detroit diesels were the same way....if you turned the motor over with the key and the engine kicked back just as you let off the key it would run in reverse....so my question is....if the engine is running backwards, would I have 10 gears in reverse and 2 forward?

Tell ya what...buy me ten beers and two shots and I shall give you the answer to your riddle....

And what a lot of people do not know, that most big pile drivers are nothing more than a two stroke diesel engine, that does not have a crankshaft... To start, a winch pulls the piston up, then fuel is injected into the cylinder. then the piston is dropped, and compression ignites the fuel which drives the driver down, and the piston up, as once it reaches the top, it drops, onto a fresh charge of fuel, and just keeps going until the fuel is shut off.....

Your trivia lesson for today.....(for those that didn't know it already)

I thought a pile driver was when Hulk hogan picked up Andre the giant over his head
